Electronic Device and Method for Controlling Display in Electronic Device

1. An electronic device comprising: a touchscreen display having a display area; and at least one processor configured to: while the electronic device is in a landscape orientation, display, on the touchscreen display, a first execution screen of a first application and a first execution screen of a second application side by side, receive a first user input, on the first execution screen of the first application, to input at least one text while the first execution screen of the first application and the first execution screen of the second application are displayed side by side, and in response to the first user input, modify the first execution screen of the first application to a second execution screen of the first application, and modify the first execution screen of the second application to a second execution screen of the second application, the first execution screen of the second application including a first text entry window, and display together, on the touchscreen display, the second execution screen of the first application and the second execution screen of the second application, the second execution screen of the second application including a second text entry window.

2. The electronic device of claim 1 , wherein the first execution screen of the first application and the first execution screen of the second application are displayed in the landscape orientation.

3. The electronic device of claim 1 , wherein the at least one processor is further configured to display together, on the touchscreen display, the second execution screen of the first application, the second execution screen of the second application, and a virtual keypad, and wherein the virtual keypad is displayed in the landscape orientation.

4. The electronic device of claim 3 , wherein the virtual keypad is a single keypad.

5. The electronic device of claim 3 , wherein the virtual keypad overlaps another remaining part of the first execution screen of the first application.

6. The electronic device of claim 1 , wherein the first execution screen of the first application does not include a text entry window.

7. The electronic device of claim 5 , wherein the first user input includes a touch gesture with respect to the first execution screen of the first application.

8. An electronic device comprising: a touchscreen display having a display area; and at least one processor configured to: while the electronic device is in a landscape orientation, display, on the touchscreen display, a first execution screen of a first application and a first execution screen of a second application side by side, the first execution screen of the first application and the first execution screen of the second application occupying a substantially entire display area of the touchscreen display, receive a first user input, on the first execution screen, to input at least one text while the first execution screen of the first application and the first execution screen of the second application are displayed side by side, and in response to the first user input, display together, on the touchscreen display, a virtual keypad, a second execution screen of the first application, and a second execution screen of the second application, the second execution screen of the second application including a text entry window, wherein the second execution screen of the first application, the second execution screen of the second application, and the virtual keypad substantially occupy an entire display area of the touchscreen display.

9. The electronic device of claim 8 , wherein the first execution screen of the first application and the first execution screen of the second application are displayed in the landscape orientation.

10. The electronic device of claim 8 , wherein the virtual keypad is displayed in the landscape orientation.

11. The electronic device of claim 8 , wherein the virtual keypad overlaps a remaining part of the first execution screen of the first application.

12. The electronic device of claim 8 , wherein the first execution screen of the first application does not include a text entry window.

13. The electronic device of claim 8 , wherein the first user input includes a touch gesture with respect to the first execution screen of the first application.

14. An electronic device comprising: a touchscreen display having a display area; and at least one processor configured to: while the electronic device is in a landscape orientation, display, on the touchscreen display, a first execution screen of a first application and a first execution screen of a second application side by side, the first execution screen of the first application not including a text entry window, receive a first user input, on the first execution screen of the first application, to input at least one text while the first execution screen of the first application and the first execution screen of the second application are displayed side by side, in response to the first user input, replace the first execution screen with a second execution screen of the first application, and replace the first execution screen of the first application with a second execution screen of the second application, the second execution screen of the second application including a text entry window, and display together, on the touchscreen display, the second execution screen of the first application, a virtual keypad, and the second execution screen of the second application, wherein the second execution screen of the first application, the second execution screen of the second application, and the virtual keypad substantially occupy an entire display area of the touchscreen display.
